Jason Padgett, Light is Pi, the Shape of Pi

Light is Pi The shape of Pi by Jason Padgett

This is Pi geometrically drawn at a value of 720sin(Pi/720) with a radius of one as if it were light. Jason drew it with a pencil and paper then inverted the color so you can see it more like he does.In this drawing Jason is showing how perfect circles do not exist...anywhere in the universe. Circles are made from triangles as are all shapes and are deeply interconnected with the number Pi. The more triangles you squeeze within a certain perimeter the closer and closer you approach a circle…
